Measurement for Space Charge and Analysis on Insulation Aging Under PWM Voltage
The relationship between the space charge and the polymer residual life is studied both in domestic and abroad laboratories. An apparatus that can directly measure the space charge distribution in the polymer insulation materials is developed. Then the space charge distribution in the polymer insulation used in PWM inverter fed motors is tested. Effects of different test condition including pole voltage and frequency are investigated in order to find the aging rule and microcosmic behave of the polymer insulation which worked under the PWM voltage. After detail analysis, we can conclude that there is strong relation between the space charge distribution and the aging mechanism.
